Open[0] with CalculateOnBarClose = true

[jalexan1]

the first tick of the bar just showed up. I presume this is when OnBarUpdate() gets called.
is the price of this tick equal to Open[0]? if not, what is the opening price of this (and not the previously finished) bar?

Hello jalexan1,

Thanks for your post.

When using CalculateOnBarClose = true, the Open[0] would be the open of the latest finished bar and not of the currently forming bar. Your code would be unaware of the currently forming bar until it too closed and became the CurrentBar.

When using CalculateOnBarClose = false, the Open[0] would be the value of the first tick of the currently forming bar. In this case, CurrentBar is the currently forming bar.

When CalculateOnBarClose = true, you only get an OnBarUpdate event at the close of the bar, once per bar.

When CalculateOnBarClose = false, you will get an OnBarUpdate event on every tick (live data only, historical data is processed like CalculateOnBarClose = true).
